Zur Bestimmung der Konzentration von Partikeln in Abgasen von Kraftfahrzeugen und anderen Aerosolen werden sogenannte Opazimeter eingesetzt. Diese beruhen auf dem Lambert-Beerschen Gesetz, indem sie die Abschwächung eines Lichtstrahls in dem untersuchten Medium erfassen und auswerten. Üblich sind dabei Anordnungen, bei denen auf einer Seite einer geraden Messkammer eine Lichtquelle und auf der gegenüberliegenden Seite ein Lichtsensor angeordnet sind. Ebenso sind Messanordnungen bekannt, bei denen zur Erhöhung der effektiven optischen Weglänge Spiegelsysteme verwendet werden. Ein Messstrahl durchläuft dabei mehrfach eine lineare Messstrecke. Zur Messung sehr geringer Menge an Molekülen, wie sie z.B. in der Atmen-Luft vorkommen, sind längere Messstrecken erforderlich. Eine Verlängerung der Messstrecke durch Vergrößern der Länge der Messkammer hat zur Folge, dass die Messgeräte groß und unhandlich werden.So-called opacimeters are used to determine the concentration of particles in exhaust gases from motor vehicles and other aerosols. These are based on the Lambert-Beer law by detecting and evaluating the attenuation of a light beam in the medium being examined. Arrangements are usual in which a light source is arranged on one side of a straight measuring chamber and a light sensor is arranged on the opposite side. Measuring arrangements are also known in which mirror systems are used to increase the effective optical path length. A measuring beam passes through a linear measuring section several times. Longer measuring distances are required to measure very small amounts of molecules, such as those found in the air we breathe. Extending the measuring section by increasing the length of the measuring chamber results in the measuring devices becoming large and unwieldy.

Aufgabe der Erfindung war es, wie eine Messkammer einer Laser-Spektroskopie für eine Geruchs-/Atemgas Analyse in einem Fahrzeug miniaturisiert werden kann zur Integration in beengtem Bauraum.The object of the invention was how a measuring chamber of a laser spectroscopy for an odor/breathing gas analysis in a vehicle can be miniaturized for integration in a confined space.
Der Gegenstand des Anspruchs 1 löst diese Aufgabe. Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Definitionen, den Unteransprüchen, den Zeichnungen und der Beschreibung bevorzugter Ausführungsbeispiele.The subject matter of
Die Erfindung stellt ein Fahrzeugbedienelement bereit zum Messen von Konzentrationen von Substanzen in Ausatemluft und/oder Körpergeruch von Fahrzeuginsassen. Das Fahrzeugbedienelement umfasst wenigstens eine an oder in dem Fahrzeugbedienelement angeordnete Messkammer. Die Messkammer umfasst wenigstens eine erste Eintrittsöffnung, durch die die Ausatemluft und/oder der Körpergeruch in die Messkammer einleitbar ist und wenigstens eine erste Austrittsöffnung, durch die die Ausatemluft und/oder der Körpergeruch aus der Messkammer ausleitbar ist. Ferner umfasst die Messkammer eine Polygon-, Ellipsen- oder Kreis-förmige Querschnittsfläche. Auf Innenseiten umfasst die Messkammer reflektierend ausgebildete Wände. Außerdem umfasst die Messkammer einen an einer zweiten Eintrittsöffnung der Messkammer angeordneten Laser, der ausgebildet ist, Laserstrahlen durch die zweite Eintrittsöffnung in die Messkammer einzustrahlen, und einen an einer zweiten Austrittsöffnung der Messkammer angeordneten Detektor, der ausgebildet ist, aus der zweiten Austrittsöffnung der Messkammer austretende Strahlung zu detektieren. Des Weiteren umfasst die Messkammer eine Schnittstelle zu einer Auswerteeinrichtung, die ausgebildet ist, die Konzentrationen der Substanzen in der Ausatemluft und/oder dem Körpergeruch aus der detektierten Strahlung basierend auf einem laserspektroskopischen Verfahren zu bestimmen.The invention provides a vehicle control element for measuring concentrations of substances in exhaled air and/or body odor of vehicle occupants. The vehicle control element comprises at least one measuring chamber arranged on or in the vehicle control element. The measuring chamber comprises at least one first inlet opening through which the exhaled air and/or body odor can be introduced into the measuring chamber and at least one first outlet opening through which the exhaled air and/or body odor can be discharged from the measuring chamber. Furthermore, the measuring chamber comprises a polygonal, elliptical or circular cross-sectional area. On the inside, the measurement chamber includes walls that are designed to be reflective. In addition, the measuring chamber comprises a laser arranged at a second entry opening of the measuring chamber, which is designed to radiate laser beams through the second entry opening into the measuring chamber, and a detector arranged at a second exit opening of the measuring chamber, which is designed to exit from the second exit opening of the measuring chamber to detect radiation.

Mit einem Fahrzeugbedienelement bedient ein Fahrzeuginsasse Funktionen eines Fahrzeuges. Das Fahrzeugbedienelement kann ein Bedienelement eines Fahrzeuglüftungs-, Heizungs- oder klimasystems sein, beispielsweise ein Touchscreen oder eine Drucktaste oder ein Drehregler. Das Fahrzeugbedienelement kann auch ein Bedienelement eines Infotainmentsystems sein, beispielsweise ein Touchscreen oder eine Drucktaste oder ein Drehregler. Nach einem Aspekt ist das Fahrzeugbedienelement ein Bedienelement, bei dessen Bedienung ein Abstand zwischen Fahrzeuginsasse und Fahrzeugbedienelement reduziert werden kann, beispielsweise durch nach vorne Beugen des Fahrzeuginsassen in Richtung Fahrzeugbedienelement. Nach einem Aspekt ist das Fahrzeugbedienelement ein Bedienelement zum Lenken des Fahrzeuges, beispielsweise ein Lenkrad oder behindertengerechte Fahr- und/oder Lenkhilfen, beispielsweise ein an einem Lenkrad anordbarer Multifunktionsdrehknauf.A vehicle occupant uses a vehicle control element to operate functions of a vehicle. The vehicle control element can be a control element of a vehicle ventilation, heating or air conditioning system, for example a touch screen or a pushbutton or a rotary control. The vehicle control element can also be a control element of an infotainment system, for example a touch screen or a push button or a rotary control. According to one aspect, the vehicle control element is a control element whose operation allows a distance between the vehicle occupant and the vehicle control element to be reduced, for example by the vehicle occupant bending forward in the direction of the vehicle control element. According to one aspect, the vehicle control element is a control element for steering the vehicle, for example a steering wheel or driving and/or steering aids suitable for the disabled, for example a multifunction rotary knob that can be arranged on a steering wheel.
Körpergeruch umfasst alle riechbaren Körperausdünstungen von Menschen über die Haut und aus anderen Körperöffnungen, wie zum Beispiel Mundgeruch. Substanzen in Ausatemluft und/oder Körpergeruch können Substanzen sein, die auf Alkohol, Kokain, Amphetamine, Cannabis, Tetrahydrocannabinol, Morphin, Methadone, Ammoniak, Azeton oder eine Kombination dieser Substanzen hindeuten. Diese Substanzen stellen Biomarker dar, die auf einen normalen biologischen oder krankhaften Prozess im Körper hinweisen können. Beispielsweise deutet ein Ammoniak-Geruch auf eine Nierenerkrankung hin. Ein Azeton-Geruch deutet auf Diabetes hin. Ein Vorteil der Bestimmung dieser Substanzen in Ausatemluft und/oder Körpergerüchen ist, dass keine chemischen Verfahren, die bei der Bestimmung des Alkoholgehalts in Atemluft beispielsweise auf ein Blasrohr angewiesen sind und damit unkomfortabel sind, oder Oberflächenkontaktverfahren, beispielsweise Adsorptionsverfahren, oder invasive Verfahren anzuwenden sind. Atemluft und andere Körpergerüche werden kontinuierlich abgegeben. Die Substanzen sind beispielsweise flüchtige organische Verbindungen, auch volatile organic compounds genannt, abgekürzt VOC. Zu VOCs gehören beispielsweise Aceton, Ethanol, Isopren, Nonanal, Decanal, α-Pinen, Buttersäureethylester und Butanal, Ethanal, Propanal und Essigsäure-n-propylester. VOC entstehen bei Lebewesen bei Protein-, Zell- oder Stoffwechseländerungen, die durch eine Krankheit ausgelöst werden. Beispielsweise wurden bei SARS-Cov-2 infizierten Menschen charakteristische Protein- und Stoffwechseländerungen beobachtet. Über Atmung und/oder Körpergerüche ausgeschiedene VOCs können charakteristisch für eine Krankheit sein und damit als Biomarker fungieren.Body odor includes all smellable body vapors from people through the skin and from other body openings, such as bad breath. Substances in exhaled air and/or body odor can be substances suggestive of alcohol, cocaine, amphetamines, cannabis, tetrahydrocannabinol, morphine, methadone, ammonia, acetone, or a combination of these substances. These substances represent biomarkers that can indicate a normal biological or pathological process in the body. For example, an ammonia smell indicates kidney disease. An acetone smell indicates diabetes. An advantage of determining these substances in exhaled air and/or body odors is that no chemical methods, which, for example, depend on a blowpipe when determining the alcohol content in breath air and are therefore uncomfortable, or surface contact methods, such as adsorption methods, or invasive methods have to be used. Breathing air and other body odors are released continuously. The substances are, for example, volatile organic compounds, also known as volatile organic compounds, or VOC for short. Examples of VOCs include acetone, ethanol, isoprene, nonanal, decanal, α-pinene, ethyl butyrate, and butanal, ethanal, propanal, and n-propyl acetate. VOCs are formed in living beings during protein, cell or metabolic changes that are triggered by a disease. For example, characteristic protein and metabolic changes have been observed in people infected with SARS-Cov-2. VOCs excreted via respiration and/or body odors can be characteristic of a disease and thus act as biomarkers.
Durch den erfindungsgemäßen Nachweis dieser Substanzen wird ein Zustand eines Fahrzeuginsassen, insbesondere eines Fahrzeugführers, hinsichtlich Krankheiten und Beeinträchtigungen der Fahrzeugführung bestimmt. Werden diese Substanzen oberhalb eines jeweiligen vorgegeben Schwellenwertes bestimmt, insbesondere bei Fahrtantritt, wird nach einem Aspekt beispielsweise eine Wegfahrsperre aktiviert, beispielsweise eine Alcolock oder Alkohol-Zündschlosssperre, die ab einem bestimmten Wert an Atemalkoholgehalt des Fahrzeugführers das Anfahren des Fahrzeugs blockiert.By detecting these substances according to the invention, a condition of a vehicle occupant, in particular a vehicle driver, is determined with regard to illnesses and impairments in driving the vehicle. If these substances are determined above a given threshold value, especially when starting the journey, an immobilizer is activated according to one aspect, for example an alcolock or alcohol-based ignition lock, which blocks starting of the vehicle from a certain level of breath-alcohol content of the vehicle driver.
Die erste Ein- und Austrittsöffnung ermöglichen, dass ein Volumen der aktuell zu analysierenden Ausatemluft und/oder des Körpergeruchs in der Messkammer homogen verteilt ist.The first inlet and outlet openings allow a volume of the exhaled air to be analyzed and/or the body odor to be homogeneously distributed in the measuring chamber.
Durch die reflektierend ausgebildeten Innenseiten der Wände der Messkammer werden die Laserstrahlen innerhalb der Messkammer mehrfach an den Reflexionsflachen reflektiert. Damit wird eine Weglänge in der Messkammer zurücklegt, die größer als ein Durchmesser der Messkammer ist. Damit wird eine miniaturisierte, in einen Fahrzeuginnenraum anordbare Messkammer mit kompakter Baugröße für die Geruchs-/Atemgas Analyse in einem Fahrzeug realisiert. Damit wird eine Messkammer bereitgestellt, die trotz geringer Baugröße eine hohe Sensibilität aufweist und daher zur Messung von Substanzen in Ausatemluft und/oder Körpergeruch in Fahrzeugen geeignet ist.Due to the reflective inner sides of the walls of the measuring chamber, the laser beams inside the measuring chamber are reflected several times on the reflection surfaces. This covers a path length in the measurement chamber that is greater than a diameter of the measurement chamber. In this way, a miniaturized measuring chamber that can be arranged in a vehicle interior and has a compact size for odor/breathing gas analysis in a vehicle is realized. A measuring chamber is thus provided which, despite its small size, has a high level of sensitivity and is therefore suitable for measuring substances in exhaled air and/or body odor in vehicles.
In der Form eines Polygons angeordnete Reflexionsflächen ermöglichen es, den Reflexionswinkel gezielt auf einen gewünschten Wert einzustellen.Reflective surfaces arranged in the shape of a polygon make it possible to set the reflection angle to a desired value.

Nach einem Aspekt umfasst die erste Eintrittsöffnung und/oder die erste Austrittsöffnung einen Filter zum Filtern der Ausatemluft und/oder des Körpergeruchs und/oder ein Ventil zum Regeln und/oder Steuern eines Durchflusses der Ausatemluft und/oder des Körpergeruchs durch die Messkammer. Der Filter dient beispielsweise dazu, ein Signal-Rausch-Verhältnis zu verbessern. Das Ventil verbessert die Verteilung der zu analysierenden Ausatemluft und/oder des Körpergeruchs in der Messkammer. Nach einem Aspekt umfasst die erste Eintrittsöffnung einen Ventilator zum Ansaugen der Ausatemluft und/oder des Körpergeruchs.According to one aspect, the first inlet opening and/or the first outlet opening comprises a filter for filtering the exhaled air and/or the body odor and/or a valve for regulating and/or controlling a flow of the exhaled air and/or the body odor through the measuring chamber. The filter is used, for example, to improve a signal-to-noise ratio. The valve improves the distribution of the exhaled air to be analyzed and/or the body odor in the measuring chamber. According to one aspect, the first inlet opening comprises a fan for sucking in the exhaled air and/or body odor.
Nach einem weiteren Aspekt umfassen die Innenseiten der Wände der Messkammer beheizbare Reflektoren, beispielsweise in Form von beheizbaren Spiegeln. Damit wird eine Kondensation innerhalb der Messkammer vermieden. Die Reflektoren werden beispielsweise auf eine Temperatur von mindestens 19°C beheizt.According to a further aspect, the insides of the walls of the measuring chamber include heatable reflectors, for example in the form of heatable mirrors. This avoids condensation inside the measuring chamber. The reflectors are heated to a temperature of at least 19°C, for example.
Nach einem weiteren Aspekt umfasst das Fahrzeugbedienelement wenigstens eine Vibrationsquelle zum Reinigen der Innenseiten, insbesondere zum Reinigen der Reflektoren gegen Anhaftungen. Die Vibrationsquelle kann beispielsweise eine Ultraschallquelle sein.According to a further aspect, the vehicle control element comprises at least one vibration source for cleaning the insides, in particular for cleaning the reflectors against buildup. The vibration source can be an ultrasound source, for example.
Nach einem weiteren Aspekt ist die Auswerteeinrichtung in dem Detektor oder in dem Fahrzeugbedienelement integriert. Beispielsweise ist der Detektor ein System-on-Chip.According to a further aspect, the evaluation device is integrated in the detector or in the vehicle control element. For example, the detector is a system-on-chip.
Nach einem weiteren Aspekt bestimmt die Auswerteeinrichtung ein Spektrum, beispielsweise ein Absorptions- oder Emissionsspektrum. Ferner führt die Auswerteeinrichtung ein Computerprogramm aus. Das Computerprogramm umfasst Befehle, die bewirken, dass ein Maschinenlernmodell, das auf Bildklassifizierung trainiert ist, auf dem Spektrum die Konzentrationen der Substanzen in der Ausatemluft und/oder dem Körpergeruch inferiert.According to a further aspect, the evaluation device determines a spectrum, for example an absorption or emission spectrum. Furthermore, the evaluation device runs a computer program. The computer program includes instructions that cause a machine learning model trained for image classification to infer the concentrations of the substances in the exhaled air and/or body odor on the spectrum.
Die Befehle, die die Auswerteeinrichtung ausführt, sind Programminstruktionen oder Hardwarebefehle. Die Befehle liegen beispielsweise als Softwarecode oder Maschinencode vor. Maschinelles Lernen ist eine Technologie, die Computern und anderen Datenverarbeitungsvorrichtungen die Ausführung von Aufgaben durch Lernen aus Daten lehrt, anstatt für die Aufgaben programmiert zu werden.The commands that the evaluation device executes are program instructions or hardware commands. The instructions are available, for example, as software code or machine code. Machine learning is a technology that teaches computers and other data processing devices to perform tasks by learning from data, rather than being programmed to do the tasks.
Nach einem weiteren Aspekt ist das Fahrzeugbedienelement ein Lenkrad. Die Messkammer ist an einem Lenkradkranz, an einer Lenkradspeiche oder an einem Lenkstock angeordnet. Damit wird einfache Benutzung für einen Fahrer ermöglicht, da durch Nachvornelehnen der Abstand zwischen Fahrer und Lenkrad beispielsweise auf unter 20 cm reduziert werden kann, was für den Nachweis der Substanzen in der Ausatemluft und/oder dem Körpergeruch vorteilhaft ist. Das Lenkrad ist beispielsweise ein Multifunktionslenkrad.According to a further aspect, the vehicle operating element is a steering wheel. The measuring chamber is arranged on a steering wheel rim, on a steering wheel spoke or on a steering column. This allows a driver to use it easily, since the distance between the driver and the steering wheel can be reduced to less than 20 cm, for example, by leaning forward, which is advantageous for detecting the substances in the exhaled air and/or the body odor. The steering wheel is, for example, a multifunction steering wheel.
Nach einem weiteren Aspekt realisiert ein Hupenknopf eines Lenkrades oder ein Halteelement des Hupenknopfes die Messkammer. Insbesondere in der Ausgestaltung, in der die Auswerteeinrichtung in dem Detektor integriert ist, wird damit ein Hupenknopf oder ein Halteelement des Hupenknopfs bereitgestellt, mittels dem die Konzentrationen von Substanzen in der Ausatemluft und/oder dem Körpergeruch von Fahrzeuginsassen messbar sind.According to a further aspect, a horn button of a steering wheel or a holding element of the horn button implements the measuring chamber.
